JEC Group have brought together the international community of composites leaders and executives in our Composites Circle as an unique networking opportunity to meet with both peers and future partners.

C3 – Carbon Concrete CompositeThe building industry has changed since the introduction of reinforced concrete. Due to corrosion the service life of reinforced concrete structures remains far behind earlier expectations - many buildings barely get older than humans and, additionally, have a high resource and energy consumption. More than 100 million cubic meters are built with reinforced concrete. It is therefore the most important building material in Germany. Concrete is the material most commonly used after water in the world which has always lead to a high consumption of raw materials. In addition it leads to enormous CO2 emissions. The production of cement is responsible for 6.5% of the total carbon dioxide emissions. That is about three times the amount of carbon dioxide emitted by global aviation.The challenges for environmental protection and the mitigation of the effects of climate change cannot be mastered without changes in the construction industry.The vision: establishing a new way to build by using C³-carbon concrete composite. Concrete will replace steel in the long term. Since carbon does not rust, most of the concrete, which is only used to protect the steel from corroding, can be spared. Carbon reinforced concrete is sustainable, environmentally friendly, saves material and weighs less. This offers a wider variety for architectural designs. Light Building and concrete are no longer a contradiction, but the concept of the future.By 2020, all conditions should be created to introduce carbon reinforced concrete onto the market. By 2025, the C³-construction should be established permanently.C³ - Carbon Concrete Composite is a research project in the German construction industry. The construction industry, with a turnover of approximately 10% of the gross domestic product and more than 330,000 companies, is the most important branch of industry in Germany. Approximately 6% of all employees work in the building industry.The Federal Ministry of Education and Research is funding the project as part of the initiative "Zwanzig20 – Partnerschaft für Innovation" (Twenty20 – Partnership For Innovation) with up to 45 million euros. All companies involved add another 15 million euros capital.GoalsAlong the entire value chain - from the basic materials to the finished building – the required knowledge must be gathered, completed by basic and applied research and transferred to the planning process, the design and the manufacture. Roughly 3,000 new jobs will be created and existing jobs will take on a new quality. The substantial quality of our buildings will increase while costs can be reduced and the resource consumption can be lowered. At the same time it has to be proved that buildings and components made of carbon reinforced concrete ensure all safety standards. This applies to all newly created buildings and components as well as for the repair and protection of existing structures e.g. bridges.Thematic emphases
PartnersThe interdisciplinary consortium currently consists of 130 partners. They cover all essential and necessary areas of expertise vital for the C³ - project. There are various industries involved in addition to the construction industry such as chemistry, mechanical engineering, engineering, electrical engineering, and the organization and communication management. Also represented are the health, the education and the training and further education sectors. 77% of the corporate partners are located in the eastern parts of Germany and 23% in the western parts of Germany. 62% of the partners are companies, 34% research institutions and 3% registered associations.More information: www.bauen-neu-denken.de
